Solve the following question:
To solve the expression , we need to follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).
Step 1: Parentheses
First, solve the expression inside the parentheses: .
Step 2: Exponents
Next, apply the exponents to the numbers:
and .
Step 3: Addition
Finally, add the results of the exponentiations:
Thus, the final answer is .

Solve the following problem:
\( 187\times(8-5)= \)
Mathematics has a specific order of operations (PEMDAS) that ensures everyone gets the same answer. Working left to right ignores exponents and gives wrong results!
means 8 × 8 = 64 (square), while means 3 × 3 × 3 = 27 (cube). The small number tells you how many times to multiply!
Yes! Always show: (1) Parentheses calculation, (2) Each exponent separately, (3) Final addition. This helps you avoid mistakes and shows your thinking clearly.
Remember: Please Excuse My Dear Aunt Sally! Or think: parentheses are like containers that must be opened first, then exponents are the most powerful operations.
Yes, but make sure you know how! For , you might press 3, then the exponent button (^), then 3. Practice with simple examples first.
